Comprehensive Bending Classification of Nucleic Acid Double Helix Structures

Bending classification of helical axis - Double-kink line
(Last update: November 15, 2004)

The following tables include structures with 13 or more base pairs given sigma2(double-kink line) is smaller than the corresponding values of the competing models. In Tables 1 and 2 structures are listed for which the central segment consists of at least 2 base pairs.

Two duplex structures with a small and a large twist angle o are shown. More detailed visual and other information for all tructures can be obtained from the links given in the Table.
